Optical Illusions

Anti-Gravity Mirror

Here’s an exhibit where watching is at least half the fun. You can create any number of gravity-defying illusions that will amaze you and your friends: Levitate, fly, swim though the air, grow limbs (and dissolve them), crawl straight up the wall like a lizard—the sky’s the limit.

Giant Mirror

This giant mirror was originally part of a flight simulator. Its size and near-perfect smoothness makes for astonishing optical (and acoustic) effects.

Gray Step

With the rope hanging down, the left and right sides of the board appear identical. Lifting the rope shows the dramatic difference that your eyes missed—and continue to miss, as soon as you let the rope fall again.
